Medical-grade hydroxocobalamin injection (5mg/vial) formulated for rapid B12 deficiency correction. Clinically validated to elevate serum cobalamin levels by 300-900pg/mL within 24 hours post-injection. Each carton contains 50×2mL sterile prefilled vials with 24-month stability under 25℃ storage. FDA-compliant production ensures ≤0.1% endotoxin levels for enhanced safety.

Bioactive Cofactor: Hydroxocobalamin acts as precursor for methylcobalamin/adenosylcobalamin with 72-hour tissue retention. Directly participates in:
• Myelin sheath regeneration (nerve conduction velocity ↑18%)
• Erythropoiesis stimulation (RBC count ↑1.5×10⁶ cells/μL)
• Homocysteine metabolism (serum levels ↓30% in 4 weeks)
